液芯微囊的制备及其应用研究进展

Research Progress on Preparation and Application of Microcapsules

近几年来,聚合物微囊被广泛应用于各行业中,其中液芯微囊因为其具有一般固体微球所不具备的特性,在食品行业,医药行业,纺织行业等进行了大量尝试与应用。本文旨在对液芯微囊的制备及其应用进行全面的阐述。目前有很多制备确切性质的聚合物微囊方法,包括胶体微囊制备法,聚合物沉淀相分离法,表面缩聚法,层-层聚电解质组装微囊,表面聚合共聚物微球,聚合物囊泡等方法。本文同时阐述了不同方法所制备微囊所具有的优缺点,以及使用不同方法制备的微囊在不同领域的应用。

In recent years, due to the characteristics of the liquid-core polymer, microcapsules are unique to the solid - core microparticles, and they have been widely used in many industrial areas, such as food industry, pharmaceuticals industry and textile industry. The application and the preparation of microcapsules were elaborated. There were many methods for preparing exact polymeric microcapsules, such as the preparation of colloidal microcapsules, the phase separation to precipitate the polymer, the interfacial polycondensation method, a layer - layer assembly polyelectrolyte microcapsules. The growth surface of the polymer microspheres was polymerized to form a polymer vesicle. Meanwhile, the advantages and the disadvantages of all kinds of them and the application in different areas were discussed.
